To all wh om t may concern: I

Be it known that we, FRAN M. BOWMAN, of Bellevue, and ALEXANDER H.BOVARD, of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in BoltDevices, of which the following is a specification.

The prime object of our invention is to provide new and improved meansfor connecting a plurality of members, such, for example, as structuralsteel members, lying in intersecting planes.

In the embodiments of our invention as illustrated by the accompanyingdrawing, we show the connecting means in form of a bolt-device or boltcomprising a body-portion, two threaded shank-portions with thebody-portion constituting heads for the respective shank-portions.

A further object of our invention is to provide a simple and efiicientconnecting means of the character mentioned comprising an integralstructure designed to be employed in connection with standard commercialnuts for connecting members whose connected faces lie in differentplanes which intersect at an angle with each other, thereby dispensingwith the use of separable gussets, lug-angles and separable bolts orrivets as has heretofore been the practice.

In the accompanying drawing, which illustrates applications of ourinvention Fig 11 re 1 is a part elevational View and a part sectionalview of a plurality of intersecting structural steel members and ourconnecting means; Fig. 2, a similar view with the sec tion taken on lineIL-II of Fig. 1; Fig. 3, a perspective view of the connecting means orbolt-device embodying our invention; and Figs. 4 and 5 elevational viewsshowing modified forms of our invention.

Referring to the drawing, 1 designates a channel'member, and 2 and 3angle-members lying in intersecting planes and connected together by ourconnecting means.

The connecting means as illustrated and as preferred consists of abolt-device or bolt comprising in an integral metallic structure a.body-portion and two threaded shankportions, said body-portionconstituting heads for the respective shank-portions. We haveillustrated several forms of connecting means constructed in accordanceProjecting outwardly from the face 5 is a I threaded shank 7, andadapted to be mounted on said shank is a nut 8. The width of the face 5is substantially the same as the diameter of the shank-portion 7, butthe length of the face is considerably greater than the diameter of saidshank thus providing shoulders or portions a and b which are designed tobear against the member interposed between the nut 8 and the saidshoulders a and b, or as illustrated the member 1. 9 designates a secondthreaded shankmember or portion extending outwardly from the face 6'ofthe body, and this member is adapted to receive a nut 10. The axes ofthe shank-portions 7 and 9 lie in intersecting planes substantially atright angles with each other.

In the form of Fig. 4, we show a modified form of our inventioncomprising a bodyportion 4: and the shank-portions 7 and 9 disposed at adifferent angle with respect to each other than that shown by the formof Fig. 3.

Fig. 5 shows a still further modification of our invention comprising abody-portion 4 and two shank-portions 7 and 9.

hat we claim is 1. A device of the character described comprising arigid body-portion having contacting faces lying in angularly disposedplanes, a shank-portion projecting from each of the said faces, andmeans on a shank-portion for securing a member between said means andthe contacting face from which the shank portion having the securingmeans projects.

2. A device of the character described comprising a rigid body-portionhaving contacting faces lying in angularly disposed planes, ashank-portion projecting from each of the said faces, and separablemeans on a shank-portion for securing a member between said means and acontacting face.

3. A bolt-device comprising a body-portion and two-shank-portionsdisposed at an angle with each other, said body-portion constitutingheads for the shank-portions,

one of said shank-portions being threaded, and a nut on the threadedportion.

4:. A bolt-device comprising a body-portion and two threadedshank-portions disposed at an angle With each other, said body-portionconstituting heads for the shank-portions, and a nut mounted on eachshank-portion.

5. A bolt-device comprising a rigid bodyportion and two threadedshank-portions, the axes of the shank-portions being disposed in planesintersecting each other substantially at right angles.

6. A device of the character described comprising a rigid body-portionhaving contacting faces lying in angularly disposed planes, ashank-portion projecting from each face, and means coacting Withtheshank-portion for securing a member on a shank portion between thecontacting face from which the shank portion projects and said means.

7. A bolt device of the character described comprising a rigidkeystone-shaped bodyportion having fiat contacting faces lying inangularly disposed planes, a threaded shank-portion projecting from eachface, and a nut on each shank-portion.

8. A bolt device of the character described comprising a rigidkeystone-shaped bodyportion having fiat contacting faces lying inangularly disposed planes, and a shankportion projecting from each face.

In testimony whereof We afliX our signatures in presence of twowitnesses.
